BRooM-MAKlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 402,385, dated April 30, 188`9.

Application filed July 16, 1887.

To all whom t may concern:

Be it known that I, GEORGE H. BALDWIN, of Grand Summit, in the county of Cowley and State of Kansas, have invented certain new and useful Improvements in Broom-Making Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form la part of this speciiication, and in which- Figure 1 is a side View of my improved machine for stitching or fastening brooms; Fig. 2 is a top plan view of the same. Fig. Sis a vertical sectional view on line 0c, Fig. 2. Fig. 4c is a view of the staple-driver. Fig. 5 is a transverse section of the same on line y y of the latter iigure. Fig. 6 is a front view of the machine, showing the staple-driver in the vise ready to be forced through the broom. Fig. 7 is a view of the lower jaw of the vise; and Fig. 8 is a vertical sectional view ou line .e z, Fig; 6, showing the staple-driver forced through the broom and the staples having their ends clinched. v

Similar numerals of reference indicate corresponding parts in all the figures.

My invention has relation to machines for securing the wires or cords holding the broomstraws together vby means of staples straddling the said cords orwires passing through the broom and clinched on the other-side of the same, and it contemplates certain improvements in the staple-driver used in the machine for which Letters Patent No. 343,97 7 were granted to me on `the 22d day of June, 1886; and it consists in the improved construction and combination of part-s of such a machine, as hereinafter more fully described and claimed.

In the accompanying drawings, the numeral l indicates the bed-plate of the machine, which may be supported in any` suitable manner, as a bench or table, or in any other manner. To this table is secured the beam or bar 2, which forms thelower jaw of the vise for holding the broom, and a tube, 3, is secured to the upper side of this beam and serves to receive the handle of the broom heldin the vise. The outer or forward end of thebeam has a transverse plate or jaw, 4, secured to serieu No. 244,489. (No moan.)

it, which jaw is formed with a groove, 5, haV- ing a number of oblique pairs of notches or grooves, 6, in it, corresponding in number and relative distances to the staples used in the broom, and two spring-arms, 7, project forward, having their inwardly-bent ends projecting between the jaws of the vise, holding the broom from the sides. Two lips or ears, S, project upward at the front end of the lower beam, and a beam, 9, is pivoted between two uprights, 10 10, at its rear end and slides between the lips or ears at its front end.

An eccentric-cam, 11, is pivoted between the upper ends of the lips or ears and has a handle, 12, by means of which it may be turned, and the cam is provided with a laterally-projecting stud, 13, upon its face, sliding in a segmentally-slotted guide, 14, pivoted upon the beam of the upper jaw. This beam is formed with' a round recess, 15, in its upper side, corresponding to the edge of the cam, and a segmental strip orl flat bar, 16, of suitable metal, is pivoted in the forward end of the recess or groove and has its rear upwardlyprojecting end bent rearward, forming a lip, 17, through a screwthreaded perforation in which a set-screw, 1S, passes, by means of which the free end of the strip may be raised or lowered, causing the jaw of vthe vise to be forced more or less hard. against the broom clamped by it whenf the cam is tilted to bring its eccentric edge to bear against the segmental strip.

VThe forward end of the upper beam is pro` vided with a transverse bar or jaw, 19, formed with a vertical box, 20, open at'the top and bottom, and registering with the notched groove in the lower jaw. A bifurcated lever, 21, is pivoted at the ends of its arms to the outer end ofthe upper beam, and is provided with two pivoted bearing-blocks, 22, near the inner ends of the arms, and with a handle, 23, at the united ends of the arms.

The staple-driver 24 consists of a narrow box, 25, having a number of tapering teeth,

26, upon Iche lower edges of its sides, .the said a bolt, 30, inserted through the sides of the same, and the upper edge of this plunger is provided with a handle, 31. The upper sides of the plunger in the side pieces of the narrow box of the staple-driver are provided with U-shaped pieces of wire, 32, seated in the grooves.

The staple-driver is placed in the box of the upper jaw of the vise, within which a broom has already been clamped, the straws of the broom being held together with wire or twine bands, or with both, tied around the broom,

4with the knot or joint at one side of the broom, so that it maybe placed in the groove in the lower jaw and a staple may be clinched over it. The staple-driver is now forced through the broom by the bifurcated lever being tilted forward, causing the ends of the staples to be guided by the oblique notches in the groove of the lower jaw and are forced back into the broom, being thus clinched in the ordinary manner.

By having the staple-driver provided with the teeth holding the arms of the staple, staples without points may be used, although the staples may be used with pointed ends.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States-- l. In a broom-making machine, a stapledriver consisting of a narrow box having registering and tapering teeth upon the lower edges of its sides formed with grooves for the reception of the legs of the staples in their inner sides, and a flat block sliding in the box7 as and for the purpose shown and set forth.

2. In a broom-making machine, the combination of the lower jaw of a broom-holding vise formed with a groove having oblique pairs of notches in it, an upper jaw formed with a narrow box open at top and bottom and registering with the groove, a staple-driver consisting of a narrow box fitting in the box of the upper jaw and having registering and tapering teeth upon the lower edges of its sides formed with grooves for the reception of the legs of the staples in their inner sides and a fiat block or plunger sliding within the box, and means for forcing the staple-driver through the broom, as and for the purpose shown and set forth.

In a broom-making machine, the combination of the lower jaw of a broom-holding vise formed with a groove having oblique pairs of notches in it, an upper jaw formed with a narrow box open at the top and bottom and registering with the groove, a bifurcated lever pivoted upon the upper jaw with its ends and having pivoted bearing-blocks near its ends, and a staple-driver consisting of a narrow box fitting in the box of the jaw and having tapering teeth arranged in registering pairs upon the lower edges of the sides and form ed with grooves upon the inner sides for the reception of the legs of the staples and of a fiat block or plunger sliding within the box, as and for the purpose shown and set forth.

4. In a broom-making machine, the combination of a beam for the lower jaw having two uprights near the forward end, abeam for the upper jaw pivoted between upright ears at the rear end of the lower beam and having a recess in its upper side near the free end, an eccentric cam-disk pivoted between the uprights and having a handle, and a segmental strip or bar pivoted with one end in the forward end of the recess and having its rear end bent and provided with a set-screw passing through it and bearing against the upper side of the beam, as and for the purpose shown and set forth.

5. In a broom-making machine, the combination of a stationary lower jaw, a pivoted upper jaw having means for forcing it down, and a tube for the reception of the broomhandle secured to the lower jaw between it and the upper jaw, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed 'my signature in presence of two witnesses.

GEORGE H. BALDWIN.
